Ops Day Shift End
TITLE: 04/24 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Since my mid shift report (alog77381), we have been able to move SR3 and SR2 to get to a good alignment (Jenne's alog77388), and check that the squeezer also has alignment issues (alog77389), leading us to think that the OFI or surrounding baffles might be the cause of the issues (alog77392). Tony is now finishing up with an alignment with the large SR3 SR2 moves to see if we can lock like that for the night, then we will continue to understand what has changed with the OFI tomorrow.
